Although it is a sampler, it can do additiv synthesis.
I sampled a few PPG sounds with it.
I built a used $55 540 MB SCSI-harddisk into my Emax II last winter. Formating took hours. The Emax II can only use 100 times of its RAM, I got 3 MB, of the harddisk. So I may use 300 MB maximum.
The storage can no longer be equiped with more RAM, because of the missing special Emax II software. Without this sofware the Emax I would never notice the present of more RAM.
